Basic salts contain a basic ion and are formed from a base or hydroxide. They are created through the precipitation method and can be found in various products such as lead paint, agricultural lime, and insecticides. Some basic salts, like white lead and potassium cyanide, are toxic and have been banned in many countries. Sodium silicate and sodium percarbonate are used in cements and cleaning products, respectively.
Basic salt, also called alkaline salt, contains a basic ion and is used to form basic compounds. They are formed from a base or hydroxide in which the hydrogen has been replaced or partially replaced with a negative element, acid or radical. Alkali salts are formed from insoluble hydroxide compounds of alkali metals or alkaline earth metals. To be considered a basic salt, the compound must include hydroxide and other anions.
The precipitation method is used to create a basic salt out of its original context. Precipitation is where a solid is created within a liquid or other solid. This effect is achieved by using chemical processes such as carbon dioxide scrubbing. The precipitation process is often used to create pigments. Salt is often a byproduct of the desalination process when water is treated.
White lead is an early example of a widely used basic salt. It was an important element used to create lead paint and a cosmetic known as Venetian Ceruse. A big problem with white lead is its toxicity. This has led to the product being banned by many nations around the world. As a result, it is used less often by artists.
Another basic salt is calcium carbonate, which is used as an agricultural lime. The basis of this salt is found in rocks such as chalk, limestone and marble, where it often causes hard water. It is also found in the shells of snails, crabs and eggs. Calcium carbonate is created by calcining calcium oxide, then mixing it with water to produce calcium hydroxide. This is then mixed with carbon dioxide.
Potassium cyanide is a more dangerous basic salt. It forms as a colorless crystalline structure similar to sugar granules. It is highly soluble in water and is used by insect collectors as a quick killing method and will not harm the specimen being collected. It is created by mixing hydrogen cyanide with potassium hydroxide.
Sodium silicate is a basic salt used in cements and as a natural fire protector. Also called a water glass or liquid glass, it is created by mixing soda ash with silicon dioxide. As a result, it produces sodium silicate and carbon dioxide.
Cleaning products like bleach are made greener and greener by using a basic salt called sodium percarbonate. It can also be used as an oxidizing agent in laboratory experiments. Sodium percarbonate is created by mixing sodium carbonate with hydrogen peroxide. The resulting mixture is then crystallized.
